If you find that your fingers are intermittently numb, especially the thumb, index finger, and middle finger, and you frequently experience neck and shoulder pain, as if something is pressing on them, along with symptoms such as dizziness, tinnitus, nausea, and vomiting, it is advisable to go to the hospital for a check-up to confirm if there is a cervical spine issue.
Frequent finger numbness is 70% likely to be caused by cervical spondylosis.
For patients with cervical spondylosis, the segments being compressed vary, and the location of finger numbness differs accordingly.
Thumb and Index Finger Numbness: This may indicate compression at the C5/C6 segment, affecting the C6 nerve root.
Index and Middle Finger Numbness: This may indicate compression at the C6/C7 segment, affecting the C7 nerve root.
Little Finger and Ring Finger Numbness: This may indicate compression at the C7/T1 segment, affecting the C8 cervical nerve root.
Ulnar Side Forearm Numbness: This may indicate compression at the T1 thoracic nerve root, leading to abnormal skin sensation and numbness on the ulnar side of the forearm.
